Weighted Average Shares Outstanding

NOTE 4. WEIGHTED AVERAGE SHARES OUTSTANDING

Below is a reconciliation of basic to diluted shares outstanding:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010
Basic		226.0		234.3		227.7		235.5
Dilutive effect of shares issuable under stock-based compensation plans		3.0		1.4		3.0		1.6
Diluted		229.0		235.7		230.7		237.1
Anti-dilutive options to purchase common shares and restricted stock excluded from the table above		10.7		16.0		10.8		16.3

The calculation of diluted EPS requires certain assumptions regarding the use of both cash proceeds and assumed proceeds that would be received upon the exercise of stock options and vesting of restricted stock outstanding as of September 30, 2011 and 2010. These assumed proceeds include Excess Tax Benefits and any unrecognized compensation of the awards.
